Much slower unlock in the Windows app

On my PC (CPU Intel® Core™ i7-6700K) with the same KDF parameters (Argon2id, 10 iterations, 128 MB, parallelism 8) vault unlock in the Windows standard app is 2 times slower than in the Chrome extension and in the web app (4 seconds vs. 2 seconds). If I set memory to 256 MB, it doubles (8 seconds vs. 4 seconds). Why could it be? Is it possible to fix this?

This is because the desktop app fails to load an optimized implementation of argon2. Your doubling in unlock time exactly corresponds with the slowdown caused by the bug.

I have an open Pull-request fixing the issue here:

But it has not been addressed yet.
